In the embodiment disclosed in Figure 1, two tools are employed designated, respec- 3 tively, l2'and 13, thetool 12 operating in advance of thetool 13, but all moved from a single operating source, such as draft animals or a tractor. p I

Beferring'first to the tool 12, a frame is provided, comprising side members 14:,preferably of'fchannel iron, these side frames being connectedbyfront and rear cross struts 15 and 16 and intermediate cross struts, two of which are shown at These struts are all provided with terminal ears 18' located in the channels of the side members 14 and connected thereto by vertical pintles .19 passing. through said ears and secured in the side members. A flexible frame is thus provided; r

2 Depending from the side members 14' are brackets,jcoinprisingiupper sectons 20 and lower sections 21; "The'npper sections are bolted, or otherwise secured, to the sidemem- 5 bers l4 and have inturned cars 22. The lower sect-ions 21 are secured to the outel.

' Shafts.

7 is a view in elevationof one of sides'of-the upper sections 20, and. have in- I turned ears 23 underlying the ears. 22. Boxes 24 areinterposed betweenthe cars 22 and 23, and have pivotal bearings 25 in said ears. Cross shafts are provided, having body portions-'26 that are angular in cross section, with: cylindrical gudgeons 27 that are journaled in the boxes 24, and on the angular portions 26 of said cross axles are mounted disks27 having angularopen ings 28 through their centers to receive the he disks are spaced apart by thimloles 29 on said shaft '26 between the said disks. their neighbors by thimbles 3O 2 having flanges 31 that bear againstthe inner sides of said end disks. Collars-32 are located on the shafts 26 on the outer sidev of the end disks, and are secured in place by set screws The brackets 20-21 are so located that the shafts 27' are directly beneath-the intermediate cross struts l7, and saidcross struts carry cleaners for the disks. These cleaners are preferably in the form of plates 3st that The end disks are spaced. from,

depend from the struts 17 and are slotted,

as shown at 35, to receive the disks. 'For the purpose of: moving the tool. a draft member is employed, in the form of a tongue. This tongue 'is made up of Sece tions 36 and 37. The section 36 overlies the front strut 15 and the two intermediate struts l7, and has a pivotal connection 38 with a. bracket 39,secured to. the rear intermediate strut 17, as illustrated in Figure 3. The front end of the/section 36 is downturned, as shown at 40 and terminates in a horizontal ear 4:1 resting upon and bolted, as shown at42, or otherwise secured, to the section 37. Said section 3.7 underlies the front strut l5, and has an upturned rear end 4&3 in rear of said strut which upturned end is bolted or otherwise secured, as shown at ts to the section 36. The draft member or.

tongue thus embraces the strut 15. The section 36. carries a foot piece 45, in which is mounted the standard 46. of asset 47 and afoot piece 48 for the operator is carried by standards 49 secured to the front strut 15 on opposite sides of the tongue. The lateral movement of the tongue with respect to. the frame of the tool, is governed by cable members, prererably'inthe form of chains 5O secured to lthe tongue section 3.7; and con-. nected to the front ends of the side members 14. This latter connection is preferably to vertical plates 51 bolted, as shown at to the frame members 1t and shown in detail in Figu e 6.

Associated with the above described tool the second tool 13. lhe specific structure of this latter tool 18 is made the subjectmatter of another application, Serial No. (317,123 filed simultaneously herewith. It is therefore unnecessary to go into detail re garding the same in this application. Slit lice it to state it consists of a frame 57 car rying spring barrow teeth 68 and other suitable instrumentalities, as for example, clearers (it). This second tool is connected to the first tool by crossed cables in the form of chains 70 connected at the front corner if of the rear frame, and to the rear corners T2 of the front frame. These connections are preferably of the same character as that dir closed in Figure (3.

\Vith this construction, when the apparatus moved along the ground to be treated, obviously the disks of the first implement will cut or score and agitate the surface and will be followed by the spring teeth which will further prepare and agitate the ground, leaving it in smooth condition. The front frame being: flexible, and the mountings of the crossed shafts tlliUiYlliQl'l1lSil(Xill;ili itw ment, the apparatus will not only conform to the ui'ievenncss of the surface, but turns can be made without creating an abnormal draft on the animals or tractor and without creating undue strain on the parts. The structure is obviously relatively simple and the parts are durable \\'llll\ a maximum of work can be accomplished with a minimum amount of time andpower and with relative ease of manipulation.

From the foregoing, it is thought that the construction, operation and many advantages of the herein d ribcd invention will be apparent to those is tilled in the art, without il'urther description, and it. will be understood that various changes: in the sire shape. proportion and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the adran tages of the invention.

Having; thus fully described my invention. what 1 claim as new. and desire to secure by Letters Patent, is?

l. in an agricultural tool. the combination with a frame, comprising side n'lembers and cross struts pivoted thereto. or" brackets de' pending from the side l1lt11llJt-3l= boxes pirol ed on upright axes in the brackets, cross shafts having their ends in the lnnzes, and disks on the shafts.

2. In an agricultural tool. the combination with a frame, comprising side members and cross struts pivoted thereto, of brackets depending from the side members, boxes pivoted on upright axes in the brackets, cross shafts that are angular in cross section and have e vlinrhical ends 'journalcd in the boxes, disks located side by side on the shafts and spacing elements interposed between the disks,

3. in an agricultural tool. the combination with a frame, comprising side members and. cross struts pivoted thereto, of depending brackets secured to the side members and comprising sections fastened together and having; inset upper and lower ears, a box pirated to and between the ears of each bracket. cross shafts journaled in the boxes, and disks located on the shafts.

it. In an agricultural tool. the COll'llJll'ltililOll with a frame, comprising side members and. cross struts pivoted to the side members, of cross shafts having pivotal mountings on the side members below the cross struts, dial-rs on the shafts. and cleaners for the disks depend ing from the cross struts and extend" iugr between said disks.

5. in an :ra'ricultural tool, the combination with a frame, comprising side members and cross struts pivoted to the side members, of brackets depeiuliire from the side members in line with the cross struts, boxes -pi\"otall y mounted in the brackets, cross shafts j()\llnaled in the boxes, disks on the shafts, and cleaners for the disks depending from the cross struts.

(3. in an agricultural tool, the combination with a frame, comprising side members and cross struts pivoted to the side members, of earth agitating iinplen'ients carried by the frame. a draft member pivoted to one of the cross struts in rear of the front end of the frame. said draft member having sections extendingboth above and below one of the struts in front of its pivotal connection, and cable connections between the front ends of the side nn mbers and the draft member.

7. in an agricultural tool, the combination with a frame, comprising side members, front and rear and intermediate cross struts piroted to the side members brackets depending from the side members below the inlernna'liate struts, boxes pivotally mounted in the brackets. cross shafts journaled in the boxes, disks on the shafts, cleaner plates dcpemlbra from the intermediate struts and slotted to receive the disks. :1. draft member pivoted to one o f the intermediate struts and having; sections embracing the front strut. and cables connected to the front ends of the side members and to the draft lIlCllllJGI in front of the frame.
